Just the presence of a hw frames context is not enough to detect whether
the transfer is an upload or a download, because hw frames mapped to
system memory will have a hw frames context attached.
D3DLOCK_READONLY properly corresponds to the absence of the write flag,
not to the presence of the read flag, while D3DLOCK_DISCARD is
equivalent to the overwrite flag.
With apple tools, the linker fails with errors like these, if the

We reset .Lpic_gp to zero at the start of each function, which means
that the logic within movrelx for clearing gp when necessary will
be missed.
This fixes using movrelx in different functions with a different
helper register.

hwcontext: clarify the behaviour of transfer_data() for cropped frames
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
The Intel binary iHD driver does not support the
VASurfaceAttribMemoryType, so surface allocation will fail when using
it.
(cherry picked from commit 2124711b950b03c582a119c75f52a87acc32d6ec)
If no string argument is supplied when av_hwdevice_ctx_create() is
called to create a VAAPI device, we currently only try the default
X11 display (that is, $DISPLAY) to find a device, and will therefore
fail in the absence of an X server to connect to. Change the logic
to also look for a device via the first DRM render node (that is,
"/dev/dri/renderD128"), which is probably the right thing to use in
most simple configurations which only have one DRM device.
(cherry picked from commit 121f34d5f0c8d7d376829a467590fbbe4c228f4f)
The driver being used is detected inside av_hwdevice_ctx_init() and
the quirks field then set from a table of known device. If this
behaviour is unwanted, the user can also set the quirks field
manually.
Also adds the Intel i965 driver quirk (it does not destroy parameter
buffers used in a call to vaRenderPicture()) and detects that driver
to set it.

Uploading/downloading data through VPP may not work for some formats, in
that case we can still try to call av_hwframe_transfer_data() on the
child context.

Certain pixel formats (e.g. P8) might not be supported for
download/upload through VPP operations, but can still be used otherwise.

When using GPU surfaces with QSV, one needs to supply a frame allocator,
which will be invoked to pass surface pools to libmfx.
For encoding, this allocator gets invoked not only for the pool of input
frames, but also for a separate pool of (apparently) reconstructed frames
and another pool of MFX_FOURCC_P8, which on Windows needs to return
D3DFMT_P8 D3D surfaces. Those are probably used to store the encoded
bitstream on the GPU.

Adds the new av_hwframe_map() function, which allows mapping between
hardware frames and normal memory, along with internal support for
implementing it.
Also adds av_hwframe_ctx_create_derived(), for creating a hardware
frames context associated with one device using frames mapped from
another by some hardware-specific means.
